Installation Instructions EXHAUSTING THE DRYER WARNING - Fire Hazard This dryer MUST be vented to the outdoors. Use only 4" rigid metal ducting for the home exhaust duct. Use only 4" rigid metal or UL-listed dryer transition duct to connect the dryer to the home exhaust. DO NOT use a plastic vent. DO NOT exhaust into a chimney, kitchen exhaust, gas vent, wall, ceiling, attic, crawl space, or concealed space of a building. DO NOT install a screen in or over the exhaust duct. DO NOT use duct longer than specified in the exhaust length table. Failure to follow these instructions can result in death or fire. EXHAUST SYSTEM CHECKLIST HOOD OR WALL CAP • Terminate in a manner to prevent back drafts or entry of birds or other wildlife. • Termination should present minimal resistance to the exhaust airflow and should require little or no maintenance to prevent clogging. • Wall caps must be installed at least 12" above ground level or any other obstruction with the opening pointed down. • Never vent the dryer out of the roof. SEPARATION OF TURNS • For best performance, separate all turns by at least 4 ft. of straight duct, including distance between last turn and dampened wall cap. SEALING OF JOINTS • All joints should be tight to avoid leaks. The male end of each section of duct must point away from the dryer. • Duct joints should be made air- and moisture-tight by wrapping the overlapped joints with duct tape or aluminum tape. • Do not assemble ductwork with any fasteners that extend into the duct. These fasteners can accumulate lint, creating a potential fire hazard. • Horizontal runs should slope down towards the outdoors 1/4" per foot. • Provide an access for inspection and cleaning of the exhaust system, especially at turns and joints. Exhaust system shall be inspected and cleaned at least once a year. INSULATION • Ductwork that runs through an unheated area or is near air conditioning should be insulated to reduce condensation and lint buildup.
